Yes I have done a long research & as well as display Altis ECU parameters myself via Toyota vehicle's interface.
Although Altis meter did not have Cruise control status lights but It's not the issue of it since ECU take over the vehicle throttle when you engage the Cruise Control & disengage throttle when you press the brake or manually do it off via Cruise stick, meter only shows cruise activity status.
If Altis would have functional ECU for cruise control I may add a bulb in the meter which is intentionally left blank or may have opted to upgrade my Altis Meter with Grande WO meter which has same pins & 2-plugs like Altis 1.6.
I had also tried to do that via an Indus EX IT employee but when he Informed that they were given a program to run on ECU which locks/disable the lot of functions including Cruise Control, Immobiliser AC controls etc. options, I discontinue to do further in this regard.
